Authorities say 17-year-old Martin Quirindongo was babysitting the infant Tuesday morning while the mother was at work. Police responded to a 911 call, saying the child was unconscious when they arrived at the apartment located at the Marble Hill Houses housing project. The baby later died at a hospital.

Police have arrested Quirindongo and charged him with murder and manslaughter. The baby was of a healthy height and weight when he died.
